3. CURRENT RESEARCH INTERESTS
* Abdelmalek Bouzari is preparing a doctoral thesis ('thèse d'état') at the University of Annaba (Algeria) on "The conic sections in the Kitab al-istikmal of al-Mu'taman (11th century): Contribution to the study of the history of geometry in Andalusia and in the Maghreb".
4. NOTES AND QUERIES
This section is reserved for questions that readers would like to have answered; these are the 'queries'. The answers will be the 'notes'. If you have questions or answers about sources, dates, names, titles, facts, or other such matters related to the history of mathematics in Africa, frame them in clear and concise language and send them to the editors. If you are answering a question, make clear reference to that question. All readers may send both questions and answers. Each will be published with the name of the sender.
Professor David Singmaster (UK) sent us the following query:
* "There is a puzzle, often called Solomon's Seal, which has a small board with three holes. The loop of a string is passed through the center hole and the two ends are passed through the loop. A ring is placed on each of the strings and then each end is passed through an end hole and tied. It looks like two oops hanging off the board with a ring on each loop. The object is to get the two rings onto one of the loops. In 1975, Fred Grunfeld's Games of the World, p. 267, calls this 'an African puzzle'. Since then, this has been repeated in other books. However, I can find no source or evidence for this assertion. Perhaps Grunfeld first came across the puzzle in Africa. In European literature, the puzzle is depicted and described as far back as 1636 in Germany, 1725 in France and 1747 in Italy. Do you know anything about this or similar topological puzzles in Africa? Indeed, anything about African puzzles would interest me."
The Solomon's Seal described is equivalent to the 'pèn' puzzle from West Africa (Guinean forest). I describe it (and some other topological puzzles) in my paper "On mathematics in the history of Sub-Saharan Africa" (Historia Mathematica, New York, Vol. 21, 1994, 345-376). Several references are indicated. My source on the 'gèn' game was the book by C. Beart: "Jeux et jouets de l'Ouest Africain", IFAN, Dakar, 1955, p. 413 (PG).
Dr. Michael Morelli (USA) sent us the following query:
* 'What do you know about math books in the 14th century university
library of Timbuktu that was uncovered by Henry Louis Gates of
* In June 1999, Abdelmalek Bouzari defended at the E.N.S.
of Algiers (Algeria) a 'Magister' thesis, entitled "The
conic sections in the Arab mathematical tradition through a treatise
attributed to al-Khazin (10th century)".
The thesis contains a historical presentation of the conic sections in the Greek and Arab traditions, a critical edition on the basis of two existing manuscripts of a text from the 10th century, attributed to the mathematician al-Khazin, and a mathematical analysis of the contents of this text.
* Also in June 1999, Khadidja Kouidri defended at the
E.N.S. of Algiers (Algeria) a 'Magister' thesis, entitled "The
method of false position in the Arab mathematical tradition".
This thesis contains an analysis of a certain number of Arab texts produced between the 10th and the 14th century, which deal with the solution of linear equations and of systems of linear equations by means of the methods of false position.

in Ethiopian history, Afrika und Übersee, 70 (1987),
" certain numbers [e.g. 2, 4, 40, 44, 80, 7] in the Semitic languages of Ethiopia form components of idiomatic expressions in which they lose their accurate mathematical significance and assume figurative meanings, or connotations which have no relation whatsoever to their original meaning. Some imply greatness, wholeness or totality; others indicate excessiveness of amount, or fantastical size" (p. 92.
Anton Vorbichler, Zahlensysteme des Balese-Obi und des Mamwu
(Mangbetu-Efe-Gruppe der zentralsudanesischen Sprachen [Number
systems of the Balese-Obi and Mamwu (Mangbetu-Efe-Group of the

* Border between two countries, collected by E. D. Earthy from
the Thonga people of Mozambique, Africa [Vol. 3(4), December 1998,
11-14], based on information contained in the book Valenga
Women, Oxford University Press, London, 1953, 95-101, written
by E.D. Earthy;
* The eagle and its nest, collected by Hugh Tracey from the Mashona people of Southern Zimbabwe [Vol. 4(1), March 1999, 11-15], based on the paper "String Figures (madandi) found in Southern Rhodesia", Southern Rhodesia Native Affairs Department Annual, 1936-37, Vol. 14, 78-88, by Tracey;
* A bed, collected by William Cunnington at the south end of Lake Tanganyika [Vol. 4(3), September 1999, 16-18], based on information contained in the paper "String figures and tricks from Central Africa", Journal of the Royal Anthropological Institute, Vol. XXXVI, 1906, 121-131 by Cunnington.
The Bulletin of the International String Figure Association
includes the paper:
* Carey C.K. Smith: String Figures from the Congo (1997, Vol. 4, 135-184). "The article presents sixty-seven string figures gathered at Upoto in the former Belgian Congo by Mrs. Ethel M. Smith during the years 1910-1914. Among her informants were members of the Lingombe, Lifoto, Ngombe, Ngwenzali, and Ngwengali tribes. Unlike F. Starr's Congo collection published in 1909, the Smith collection includes methods of construction for each figure. In an appendix to this article, the author presents methods for making thirty-nine of the sixty-two figures described by Starr." The Starr's collection may be found in the following paper:
* F. Starr: Ethnographic notes from the Congo Free State, Proceedings of Davenport Academy of Sciences, 1909, vol. 12, 148-175

New York, 1999) contains a compilation of articles from the String
Figure Magazine. It includes two figures from Africa: "A
hammock" (Zanzibar, Tanzania) and "Two eyes" (Liberia).
